Last few days been getting 22-24mpg to/from work according to the scan gauge. I'm wondering if the tailgate up/down rumor would prove good in my case with a shorter box, guessing not but I'm thinking about trying it for a day.
I received my new 235/85/16 tires, so they should be on the truck before long, and the scangauge will be off once again lol.
With small amount of research, posts suggest that the supercharger option for this engine increases mpg slightly (1-2 mpg claimed). Nothing special, but the extra power for the once in a while fun factor might be worth while. Down side is the rebuild every 100k miles (~4-5 years for me) but +75hp is nice  .
Really need to get a notepad in the truck so I can start my fuel log. |
Tailgate up vs down isn't likely to be a large change in drag, but everything I've seen in the past indicates tailgate up should offer a slightly better trailing wake.
I could be wrong, but I was under the impression that the supercharger would create a less efficient bottom end torque curve in exchange for more top end power. I look forward to your results.
I also experience a 10-15% decrease in FE with 4x4 engaged. It's worth every penny when you need it though (which has been allot around here the last few days).
